is provided on one of thebars, and a deformable being understood that the aluminum-steel com- 5 bination suggested above is merely for purposes of illustration.

The pressure for imbedding the teeth I2 is provided by a screw l8 bearing against the upper side of the tie bar and pressing the latter downwardly against the set-plate. After a sheet of glass has been set and the glazing bar 3 pressed forward against the glass with the hand or fingers until the proper degree of snugness is attained, the screw 18 is tightened to clamp down on the tie bar. This causes the teeth to become imbedded in the tie bar and thereby lock the sash bars 2 and 3 together. A substantially perfect fit with the glassis attained, irrespective of the thickness of the latter, because the teeth of the set-plate imbed themselves in the tie bar at any selected po- 7 members positively in position, oneto" the-other.

" The tie bar l4 may be a continuous flangeextending along the sash bar 3;.or it 'may be discontinuous, with sections projecting inwardly onlyat spaced intervals. The set-plates]! are adjustable along the bar 2 and as many as is deemed'suitable ordesirable may be provided; The clamping screws I8 are also spacedalong' the bar, as many being provided as is needed for giving the proper clamping action. The screws are preferably {positioned to lean away from the glass 4 to'give room for a workman to handle his screwdriver. To accommodate thisangle of the screws the tie bar is provided with a tapered surface, thereby giving a positive and direct'bearing for the screws.

It will be notedthat the upper flange 6 of the stationary bar 2- slopes rearwardly to providea drain passage for collected-moisture. Suitable drain holes 19 are provided along thispassage'for conducting the collected moisture downwardly; and'suitable weep holes 20 are provided in the base flange 1 for draining out the water; Suitable grooves 2! in the bottom of the glazing bar 3.

cooperate with the weep holes to provide for ventilation. The bottom of the stationarybar 2 is pre'ferably recessed, as shown in Figures 1, l0 and 1 1, for receiving a mastic cementing or sealing compound.

Figures 2 to 5 illustrate the principles of-my invention as embodied in division and corner units, where the function of the structure is to provide a joint between plates of glass. In these cases the outer or glazing. bar 22 engages or bridges the glass" panes 23,1 and the tie bar v24 projects inwardly between the glass panes. A pair of inner bars 26 are provided in this type of construction, one on each side-of the tie bar 24 and each engaging one of the glass plates 23.

The bars "26 each have alongitudinally extending groove in which is seated a set platezl, after'much the same manner of the set-plate ll described in the sash construction of Figure 1. The elements are clamped together bya suitable bolt 28 passing through elongatedapertures provided in the bars 24 and 26 and in the set plates 21." As in the sash construction, the set-plates are made of a harder material than that used in the tie bar, so that when the clampingbolt.28 is tightened the teeth of the set-plate will become irnbedded in the tie bar.

w 'The inner end of the tie hard! .is preferably provided with flanges 29, against which a tool, such as that shown in Figures 8 and 9, may engage. The purpose of this tool, as shown in Figure 8, is to provide a simple and convenient means for bringing the bars snugly against the glass panes. When the proper degree of snugness is attained the bolts 28 are tightened to lock the structure together. These clamping bolts are spaced at intervals along the unit as will be readily understood. A feature of these division and corner unit constructions is, that they are exceptionally well adapted for adjustment to accord with varying conditions in difierent installations. The fact that one glass pane may be thicker than another is conformed with by the independent action of the glass engaging bars 25. As in the previously described sash construction, the se't plates 21 cooperate with the softer tie bar 24 to securely lock the elements of the unit in a given position of adjustment. Figures .2 and 3 alsosh'ow the addition of a reinforcing member 3l comprising two sections clamped about the inwardly projecting portion of the unit'b-y suitable bolts 32. This reinforcing member adds to the rigidity of the construction, and may be found desirable under mam conditions. Of course this reinforcement may also be employed in the corner unit illustrated in Figure 4. The corner unit however is an inherently stronger construction, and the reiniorc ing consequently does not. find as many applica tions at this point of the construction.

Figures 10 and 11 illustrate a variant form-o sash construction embodying the improvements of my invention. This structure is similar to that shown in Figure 1, except that in the present instance the tie bar 33 is pivotally and slideably mounted on the glazing bar. This arrangement gives-an additional amount of adjustability. The mounting of the tie bar 33 is provided'by form ing'a cylindrically shaped socket in'the glazing bar adapted to receive 'a similarly shaped end 34 on the tie bar. The-transverse adjustment provided by the pivotal mounting of thetie bar eliminates any possibility of undue strain on the glass when thestructure is being assembled and lockedi 'The'longitudinal' adjustment of the tie bars along the sash gives a flex'ibility to the constructionwhich is-useful in the setting of the setting blocks'and in the assembly of the unit after-the pane and its blocks have been set;

Figures'10 and-'11 also illustrate a variant form of construction, in which the tie bar 33 is made of harder material than the set plate-36; the

teeth then of course being-provided on the under side ofthe bar,'as is clearly shown in Figure '11. In this construction the plate 36'Inay conven iently be of the softer metals, such as Babbitt or type'metal'. Of course it is understood that this reversal in the mountingof the teeth is ap plicable to the constructions shown in Figures 1, 2 and 4. That is, the teeth in the latter struc tures could be formed on the tie bars, andsetplates made of the softer material. 'Ihe' modified structure 'ofJFigures IO and 11 has the advantage of an independently formed tie bar. This gives a wider selection? of materials in themaking of the tie bar. .Inrthe integral construction of Figure 1 "the materials employed. in the tie bararelimited to those suitable for the glazing bar. This limitation however is not, imposed in the modified construction.

It isunderstood that :formation of the teeth on the tie bar or set-plate is subject to varia: tion withinwidc limits .Protuberancessuch as shown in Figures 6 and '7 may be provided, or teeth may be formed by knurling or scoring the surface of the metal. It is further understood that an independent set-platdneed not be provided. For example, the toothed tie bar may be imbedded directly into the sash bar. This is particularly true of the construction shown in Figures 10 and 11, where the demountable toothed tie bar may be made of 'a material selected primarily for its hardness.
